int values with string values in enum

Question

How can I make cards Enum in Java similar to:

public enum Card {2, 3, 4, 5, 6, 7, 8, 9, 10, Jack, Queen, King, Ace};

I tried {"2", "3"...}. It's not working either

Answer 1

The JLS (Java Language Specification) tells us two important facts:

1. Java enum fields must be valid identifiers.

   EnumConstants:
       EnumConstant
       EnumConstants , EnumConstant
   
   EnumConstant:
       Annotations_opt Identifier Arguments_opt ClassBody_opt
   
   Arguments:
       ( ArgumentList_opt )
   
   EnumBodyDeclarations:
       ; ClassBodyDeclarations_opt
   

2. The first character of an identifier must be a "Java letter."

   ^{The "Java letters" include uppercase and lowercase ASCII Latin letters A-Z (\u0041-\u005a), and a-z (\u0061-\u007a), and, for historical reasons, the ASCII underscore (_, or \u005f) and dollar sign ($, or \u0024). The $ character should be used only in mechanically generated source code or, rarely, to access pre-existing names on legacy systems.}

You must work within these restrictions.

public enum Card {
    Two,
    Three,
    Four,
    Five,
    Six,
    Seven,
    Eight,
    Nine,
    Ten,
    Jack,
    Queen, 
    King,
    Ace;
}
